In Illinois the Maysvillian Stage consists of strata in the upper part of the Scales Formation, including the Upper ''Depauperate'' Zone and the overlying argillaceous limestone beds that contain ''Isotelus'' in abundance. The Girardeau Limestone in the extreme southwestern part of Illinois is approximately at this position, but its relation to the Upper ''Depauperate'' Zone is not known. Its fauna has long been considered to be more closely related to Silurian than to Ordovician faunas (Savage, 1917), and it therefore probably is late Richmondian in age.<br />
